Executive Summary

While many different simulation tools are available to compute MIMO capacity and diversity gain system performance, few works tackle the problem from the measurements standpoint. In this paper, several measurements of MIMO capacity and diversity gain performance of dipole antenna arrays are performed through the use of a reverberation chamber, which includes many effects present in real MIMO channels but generally avoided in simulations. Results show that polarization diversity can be effectively combined to spatial diversity even for Rayleig-fading MIMO scenarios to achieve increased diversity gain and MIMO capacity.
